Precision tube is a kind of cold drawn or cold rolled seamless steel tube production process of high precision and high brightness by. The inside and outside diameter sizes can be accurate to 0.2mm, and the utility model can be widely used for the manufacture of precision mechanical parts and engineering structures when the bending and torsional strength are the same. Also used for production of various conventional weapons, barrel, shells, bearing etc.. According to th...

Clean Application of solvent, emulsion cleaning steel appearance, to remove oil, grease, dust, lubricant and similar organic matter, but it can't remove the steel surface rust, oxide, flux, and the only accessory as produced in corrosion. 2. Derusting tools The primary use of wire brush tools such as grinding of steel surface, can remove the loose or tilt of the scale, rust, welding slag etc.. Hand tools rust can reach Sa2 level, Powertool cleaning can reach ...

Some small, thin steel plate, steel, silicon steel sheet, small caliber or thin-walled steel tube, cold rolling, cold drawn steel and high price, easy corrosion metal products, can be stored in storage. Keep the site or warehouse of spiral steel pipe products, should be selected in the clean, unobstructed drainage areas, ...
Continue Reading>>The production process is different, the spiral pipe is made of steel strip crimp welding, seamless tube is made of billet into a square tube without welding points. Use is different from the spiral tube pressure is not as good as the seamless square tube pressure is high, the price is different, seamless square tube production capacity is low, the spiral tube production capacity is high, two kinds of the same type of square tube seamless square tube expensive , If not th...

Usually, the fluid is pressurized by air blower, compressor, pump and boiler, which can be used to the low pressure from the high pressure of the pipeline. Pipeline is widely used in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering and a variety o...

The processing of spiral steel pipe in the diameter and wall thickness of the size of the specifications have greater flexibility, especially in the production of high-grade thick-walled pipe, especially in small and medium-sized thick-walled pipe with other technology can not match the advantages to meet the user In the spiral steel pipe specificatio...
Continue Reading>>Spiral welded steel pipe forming process, the steel plate deformation uniform, residual stress is small, the surface does not produce scratches. Machined spiral steel pipe in the diameter and wall thickness of the size range of greater flexibility, especially in the production of high-grade thick-walled pipe, especially in small and medium-sized thick-walled pipe with other processes can not match the advantages to meet the user In the spiral steel pipe specifications more re...

In the stainless steel pipe surface has a thin protective film, protective film, protective film of about 3-6 mm, the film is more tough, even if the protective film damage, as long as the oxidation, can effectively prevent its further oxidation , Produce rust. In the understanding of the characteristics of stainless steel pipe and to achieve the correct use, can effective...

Currently on the market commonly used in the appearance of processing can be used in 304 stainless steel. First, dry grinding drawing The most common on the market are filament and short wire, 304 series stainless steel through the processing of such appearance, showing outstanding decorative effect, to meet the needs of the usual decoration materials. In general...
Continue Reading>>Big diameter steel pipes, either spirally / helically seam welded or longitudinally / straight seam welded, are cold-formed and welded by submerged-arc welder or electric resistance welder. Longitudianlly seam welded pipe (SAWL) is widely used as the main pipeline for oil and gas and other fluid as well. Ez Steel LSAW plant can produce OD: 457 mm - 1422mm Length: 6000mm - 12,500mm Wall Thick: 10mm - 50mm. Material grade from S235 up ...
Continue Reading>>Hot-dip galvanized steel pipe is a hot-dip galvanized steel pipe made by bending a strip or a coil plate in a helical shape and welding the inner seam and the outer seam with double-sided submerged arc welding, which can be widely applied to water for the following reasons , Electricity, chemical and other industries: 1) As long as the change of forming angle, you can use the same width of the strip production of various caliber steel pipe, easy to adjust. 2) Because it is a ...
Continue Reading>>In the use of helical submerged arc welded steel pipe and the production process, the human invention of a lot of excellent welding and production methods, greatly promoted the steady and rapid development of the industry, but also makes the industry in the development of optimization. Which submerged arc welding is a new welding method invented in 1940, it is the same as the previous manual welding is it or the use of slag protection, but the residue is not the electrode...
